Efficient and eco-friendly extraction of corn germ oil using aqueous
An improved aqueous extraction method has been established for extraction of oil from corn germs. This method primarily included steam explosion pretreatment and aqueous ethanol extraction. Process variables such as steam pressure, resident time, particle size and ethanol concentration were investigated. The highest yield of 93.74 % was obtained when ground steam-exploded corn germ (1.3 MPa
Designed for difficult-to-process materials like corn germ, palm kernel, and grapeseed, the Duo’s unique dual-pressing action can reduce residual oils to 5-6% in a single pass. Models of this machine from the 1930s are still operating today, earning the Duo a reputation as the most durable, long-lasting press in the oilseed extraction industry.
The Corn Refining Process
The germs, containing about 85 percent of corn's oil, are pumped onto screens and washed repeatedly to remove any starch left in the mixture. A combination of mechanical and solvent processes extracts the oil from the germ. The oil is then refined and filtered into finished corn oil. The germ residue is
5.1. Corn Germ Oil. Corn germ oil is a nutritious and healthy edible oil. It has a transparent golden yellow color and a fragrant fragrance. It is called “liquid gold” by Western countries. Corn germ oil contains 80–85% of unsaturated fatty acids, oleic acid, linoleic acid, and α-linolenic acid. The content of linoleic acid is as high as
Corn Oil: Composition, Processing, and Utilization
Crude corn oil usually contains about 3% FFA and phosphorus content in the range from 300 to 1000 mg/kg. It also contains pigments, such as xanthophylls and carotenes, as well as waxes and insoluble components. This oil may also contain oxidation products, mycotoxins, and residues of pesticides and insecticides.
In general, it is verified that corn oil processing by-product has a dry matter content of 89.0%, crude protein around 10.6%, the crude fiber of 4.6%, ether extract close to 1.34%, in addition to calcium, phosphorus, several amino acids such as methionine, lysine, and tryptophan [ 22, 23, 24 ].
Oil and protein recovery from corn germ: Extraction
This work aimed the recovery of oil and protein fractions from corn germ (CG) generated as a by-product during flour processing. Several oil extraction techniques were investigated: hexane at room temperature, hexane at 45 °C, supercritical carbon dioxide (Sc-CO 2) and Soxhlet with hexane and ethanol.
Corn germ oil ( Zea mays) Corn germ oil is a by-product of the corn oil milling process. Most corn that is harvested is used as feed but the proportion of the corn that is milled is increasing because of bioethanol production. During the wet milling process, the germ is isolated from the starch using cyclone separators, washed, and dried.

The corn oil can be further refined from a crude product to an edible product. Oil Refining and Processing. Extracted and desolventized corn oil must be further processed to make an edible product. Edible oils are refined to improve the flavor, odor, color and stability using processes that degum, neutralize, bleach and deodorize the
3. Corn Husks. Corn husks are the most abundant and least valuable by-product of corn industrial processing, accounting for 10% to 14% of the total fiber content of corn [ 47 ]. Corn husks contain 382 g cellulose, 445 g hemicellulose, 66 g lignin, 19 g protein, and 28 g ash per kg of dry matter [ 48 ].
